You have a L in series with an R. You have a C in series with an R. You 
then put the series RC and series LC in parallel with each other.

Now make R=sqrt(L/C) and find the resonate frequency.

f=????

 I'll give it a try!


F=1/(2pi*sqrt(L*C))    The standard resonance equation still applies....

 But.....

At resonance XL=R and Xc=R (by your design requirement above).
Providing equal leading and laging branch circuit currents and opposite phase 
shifts;
and and overall Q=0.25

 With a Q of .25 you will have a very hard time seeing or measuring any 
'resonance' effect.
